CHARLES W. VOSKAMP, OF PITTSBURG, PENNSYLVANIA.

HORSESHQE.

SPECIFICATION forming part of Letters Patent No. 752,609, dated February 16, 1904.

Application filed October 28, 1903- Serial No. 178,852. (No model.)

To all whom, it may concern.-

Be it known that I, CHARLES W. VOSKAMJ?, a citizen of the United States of America, re-

siding at Pittsburg, in the county of Allelates particularly to that type of shoes in which I the service calks and toes are superseded or replaced by temporary ones of a different form.

Heretofore and before my invention various devices have been tried for providing sharpened calks and toes on horseshoes without the removal of the shoe from the hoof; but these devices, so far as I am aware, have generally been of a form in which the calks or toes are removed from the shoe and others substituted. Such devices have generally been found defective, as the wear to which the shoe is subjected damages the same to such an extent as to prevent the removal of the calks and toes when desired. In accordance with my invention, however, I make no alteration whatever to the calks and toes of the ordinary shoe and no alteration to the shoe except toprovide threaded openings to receive stud-bolts or screws for securing to the shoe an auxiliary shoe which is provided with calks and a toe of a form particularly adapted for use when the streets or roads are icy or covered with snow in such a condition as to require calks and toes that will prevent the slipping of the animal. This auxiliary shoe is of a contour conforming to that of the main shoe and may or detachably secured thereto, and it is adapted to fit on the underneath face of the horse'- shoe between the calks and the toe.

In the accompanying drawings I have, shown and will'herein describe in detail an embodiment of my invention without, however, limiting myself in the practice of the invention to the exact construction herein shown and described.

In the drawings, Figure 1 is an inverted detail perspective view of a horseshoe constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse vertical sectional view thereof. Fig. 4 is a longitudinal sectional view of a part of the auxiliary shoe and toe, showing a modified form of construction. Fig. 5 is a transverse vertical sectional view of the same. Fig. 6 is a cross-sectional view of a modified form of construction of securing the calks, and Fig. 7 a longitudinal sectional view of the same.

To put my invention into practice, the shoe 1 is provided with a toe 2 and with calks 3 of the ordinary form of construction, this shoe being adapted to be'nailed to the hoof of the animal in the usual manner. I provide this shoe, however, in each of its two rearwardlyextending members with threaded openings 4, which may be extended entirely through the shoe or only partially therethrough, as may be desired. My invention, as stated, resides in the auxiliary shoe or attachment adapted to be secured to the horseshoe, and to put the same into practice I provide a plate 5, shaped correspondingly to the shoe 1,'the ends of its two members being adapted to abut against the inner wall of the calks 3 and the other end of this auxiliary shoe-plate adapted to abut against the inner wall of the toe 2, as seen in Figs. 1 and 2. This plate is provided in each 5 its two members with apertures 6, which register with the apertures 4 in the shoe 1, and the apertures 6 are preferably made oblong, whereby the threaded shanks of the stud bolts or screws 7 may be the more easily and readily centered in the apertures 4. The plate 5 may be constructed with a bridge portion 8 near the toe, extending across the space between the two members of the shoe 1, adding to the strength of the auxiliary shoe. This auxiliary shoe-plate 5 carries at the extremities of its two members sharpened calks 9 and at its toe portion a sharpened toe 10. I generally prefer to weld these calks and the toe to the plate 5, though, where it is desired, the same may be secured to the plate 5 by means of screws 11, as seen in Figs. 4 to 7, and when employing this construction I generally provide two screws for each calk and three screws for the toe in order to firmly secure the same to the plate, the heads of the said screws being countersunk in the plate 5.

The holes I may be provided easily by any blacksmith when making the shoe 1, and the said shoe 1 is therefore always ready to receive the auxiliary shoe, which may be readily attached thereto either by the driver before starting out with the animal or the auxiliary shoes may be carried as a precautionary measure and attached easily, if required. The means of attaching and detaching permits of the ready removal of the auxiliary shoe when the animal is returned to the stable, which afiords considerable relief to the animal, as it is well known that to cause an animal to remain standingfor any length of time on a shoe having high calks and toe is very injurious to the animal. This is entirely obviated with my device by the detaching of the same when the animal is to be left standing in the stable.

While I have herein shown and described the invention in detail as it has been practiced by me, yet I do not wish to confine myself to the exact construction shown and described, as it will be evident that in the practice thereof various slight changes may be made in the details without departing from the general spirit of the invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with the horseshoe, an auxiliary shoe embodying a plate adapted to fit between the calks and toe of the horseshoe, with means for securing the plate to the horseshoe, calks carried by the plate at the extremities thereof, and engaging the inner wall of the horseshoe-calks, a toe carried by said plate having a straight front wall for abutting engagement with the rear wall of the horseshoetoe, and a bridge portion connecting the legs of. the plate adjacent the toe, and merging into the latter and extending to the rear of the horseshoe-toe.

2. In combination with the horseshoe, an auxiliary shoe comprising a plate fitting between the calks and toe of the horseshoe, calks and a toe carried thereby, means extending through the plate and into said calks and toe thereof for securing the latter to said plate, said means lying flush with the under side of the said plate and being engaged by the under side of the horseshoe, the calks and the toe of the plate being in engagement with the calks and toe of the horseshoe, and means for securing the plate to the horseshoe.

In testimony whereof I afiix my signature in the presence of two witnesses.
